Significant cost reductions and performance enhancements in planar magnetics have been introduced in recent years. These include replacing costly multilayer PCBs with lower-resistance flat coil ...

PI Expert, Power Integrations’ online power supply design program, now features a planar magnetics builder, along with a database of planar cores. With this update, PI Expert can generate an ...

Planar transformers and inductors for high-frequency converters differ radically from conventional magnetics in that they do not use magnet wire. Instead, windings are copper-foil lead frames or flat ...

The demand for higher efficiency and smaller packages has been the driving force behind advances in switch-mode power-conversion topologies including buck, boost, flyback, forward converters, and ...

Power Integrations has launched a new function in PI Expert, its online design tool that automatically generates optimised power supply designs based on users’ specifications. PI Expert now features a ...
